Open publisher page 1 citations

Abstract

High-accuracy horizontal position and geodetic height difference can be obtained by means of GPS technology,but in the actual application of this technology,normal height system is often adopted for surveying the height of points on ground,thus GPS geodetic height must be converted to the normal height.This paper compared the fitting accuracy of GPS height fitting method,and conducted an experiment,which comprehensively uses GPS leveling and improves the fitting accuracy.
